No.15/887,150 filed on Feb. 2, 2018 which claims the benefit of U.S.Provisional Patent Application No. 62/453,796, filed Feb. 2, 2017, andU.S. Provisional Patent Application No. 62/503,086, filed May 8, 2017,the entire disclosures of which are hereby incorporated by reference.

BACKGROUND

Electrical wall boxes are well known. A typical electrical wall boxincludes a housing that is installed within a wall. An electrical wallbox is typically configured to receive at least one electrical device,such as a switch or a receptacle, for example. A typical electrical wallbox is also configured to receive a wall plate. The wall plate may beadapted to cover a yoke plate and/or escutcheon of the electricaldevices mounted within the wall box. The wall plate may be configured tobe attached to the electrical device with or without fasteners.

An electrical wall box may be configured to receive a single electricaldevice or multiple electrical devices. An electrical wall box that isconfigured to receive multiple electrical devices may be referred to asa multi-gang wall box. Different types of electrical devices, e.g.,devices of varying size, may be installed in a multi-gang wall box.Different electrical devices may have different mounting requirements,such as different fastener locations and/or sizes, for example. And,though some electrical devices may be installed in a single wall boxwith other types of electrical devices, certain electrical devices maynot be installable in the same wall box with other types of electricaldevices. Furthermore, multiple wall boxes may be installed in closeproximity to each other, e.g., directly next to each other.

A typical wall box installation tool includes a template used forlocating a wall box. Typical wall box installation tools provide for theinstallation of a single multi-gang wall box (e.g., a two- to four-gangwall box), but do not allow for the installation of non-standard wallboxes as well as locating and aligning multiple adjacent wall boxes.

SUMMARY

As described herein, a wall box installation tool may facilitate theinstallation of one or more wall boxes for mounting electrical devicesto a wall. The wall box installation tool may be configured to aide inthe marking and/or drilling of pilot holes required for installing thewall boxes. The wall box installation tool may be used to install one ormore multi-gang wall boxes that have either standard or non-standardspacing between gangs. The wall box installation tool may help withachieving the appropriate spacing between and alignment of adjacent wallboxes. The wall box installation tool may be configurable to allow forthe installation of wall boxes for electrical devices having differentsizes and/or configurations, for different numbers of electrical devices(e.g., different number of gangs), and/or for different spacings betweenelectrical devices and/or other wall boxes.

The wall box installation tool may include a template body and atemplate card. The template body may include a front surface, a guidering that extends from a rear surface of the template body, and aplurality of bores that extend through the template body from the frontsurface to the rear surface. The guide ring may be configured to beinstalled within a pre-drilled hole in a wall. The guide ring may beconfigured to position the wall box installation tool within a wall.

The template card may be associated with an electrical deviceconfiguration of the electrical devices that may be mounted to the wallbox. The template card may have a plurality of holes therethrough. Whenthe template card is installed on the front surface of the templatebody, a subset of the bores in the template body are accessible via theholes of the template card. The template card may be removed from thetemplate body and another template card may be installed on the frontsurface of the template body. The second template card may have aplurality of holes in different locations than the holes of the firsttemplate card, such that a different subset of the bores may beaccessible via the holes of the second template card. A number of theplurality of holes of the template card may be less than a number of theplurality of bores of the template body.

The second template card may be held against the front surface of thetemplate body and may be moved on the template body from a firstposition associated with a first electrical device configuration to asecond position associated with a second electrical deviceconfiguration. For example, the template card may be slid along thefront surface of the template body between the first and secondpositions. A first subset of the bores may be accessed via the pluralityof holes when the template card is in the first position. A secondsubset of the bores may be accessible via the plurality of holes whenthe template card is in the second position. The wall box installationtool may comprise two template cards that each may be slid from a firstposition to a second position. A first subset of bores may be accessiblevia the first and second template cards in the first position, and asecond subset of bores may be accessible via the first and secondtemplate cards in the second position. In addition, a third subset ofbores may be accessible via the first and second template cards whenfirst template card is in the first position and the second templatecard is in the second position.

The wall box installation tool may be used to drill one or more pilotholes associated with the configuration of electrical devices that areto be installed in one or more wall boxes. For example, the guide ringof the wall box installation tool may be inserted in a first holedrilled in a wall. The wall box installation tool may include a levelthat may be used to level the wall box installation tool when installedin the wall. The template card(s) may be adjusted to correspond tovarious electrical device and/or electrical wall box configurations. Forexample, if the wall box installation tool has two template cards, thefirst template card and the second template card may be moved intoposition based on a selected configuration of electrical devices. One ormore pilot holes may be drilled at the locations of the holes and boresassociated with the selected positioning. The wall box installation toolmay be removed from the wall and one or more second holes (e.g., 68 mmdiameter hole) may be drilled at the location of the one or more pilotholes. Remaining wall material between the first hole and the secondhole may be removed to allow for installation of one or more wall boxes.

A wall box installation tool that includes a template body, andplurality of levels is also described herein. The template body may havea guide ring and a plurality of bores that extend through the templatebody. The guide ring may extend from a rear surface of the templatebody, and may be configured to be installed within a pre-drilled hole ina wall. The plurality of levels may be positioned at oblique angles onthe template body. A first subset of the bores may be aligned with afirst level of the plurality of levels, such that the first subset ofthe bores may be horizontal when the first level is level. A secondsubset of the bores may be aligned with a second level of the pluralityof levels, such that the second subset of the bores may be horizontalwhen the second level is level
